DTC codes / P2Axx · Hybrid propulsion / P2A2F
P2A2F indicates that the powertrain control module (PCM) has detected a performance fault or a stuck-off condition in the control circuit for the alternative fuel tank shutoff valve E. The PCM commands the valve to open or close and monitors the circuit for expected voltage or current changes; when the response does not match the command, this code is stored.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
